Method of forming roll



R. H. CLINE METHOD OF FORMING ROLL Original Filed Oct. 21, 1954 June 6,1961 INVENTOR. ROBERT CL/NE M ,6 a V A T TORNE Y United States Patent P4 Claims. (Cl. 154-117) This invention relates to a method of forming aroll of absorbent material or the like on a cable, such roll and cablebeing particularly useful in an applicator for applying insecticide toanimals, such as cattle, wherein the animal itself furnishes therelative movement between the applicator and the animal. Thisapplication is a division of my copending application Serial No.463,686, filed October 21, 1954, and entitled Animal InsecticideApplicator, now U.S. Patent No. 2,835,225.

In my copending application Ser. No. 463,686, there is disclosed andclaimed an insecticide applicator, in which a roll of absorbent materialis mounted on a cable which is preferably mounted so as to extend at anangle to the ground, the absorbent material being enclosed within ajacket of relatively heavy woven material, which also extends over areservoir adapted to contain an insecticide solution, disposed at theupper end of the roll and also rotatable about the cable. The applicatoris engaged by an animal rubbing against the same, who receives theinsecticide solution through the roll and the covering. While such aroll may be wound tightly about a cable, it normally tends to remainfixed in position on the cable after installation and an undue amount ofwear is caused by animals rubbing against essentially the same spot onthe jacket, thereby causing the jacket to wear out relatively quickly.Thus, it is highly desirable to provide a roll of absorbent material ona cable which may move relatively thereto during use.

Among the objects of the present invention are to provide a novel methodof forming a roll of absorbent material on a cable to provide such amethod which permits the roll to move relative to the cable afterinstallation; to provide such a method in which the roll may be rolledabout the cable as tightly as desired; and to provide such a methodwhich is simple but effective in use.

Additional objects and the novel features of this invention will becomeapparent from the description which follows, taken in connection withaccompanying drawing, in which:

FIG. 1 is a front elevation of an applicator in which a roll formed inaccordance with this invention is particularly useful;

FIG. 2 is a longitudinal section of a roll and associated parts, forminga portion of the applicator;

FIG. 3 is an enlarged cross section taken along line 33 of FIG. 2;

FIG. 4 is a fragmentary enlarged view, taken at the end of a layer ofabsorbent material preparatory to rolling the same onto a wire rope orcable;

FIG. 5 is a fragmentary cross section showing the absorbent materialrolled onto the cable;

FIG. 6 is a similar cross section showing theroll after release so thatit may rotate about the cable or move longitudinally thereof; and

FIG. 7 is a fragmentary, enlarged longitudinal section of a solutionreservoir and associated parts.

An applicator A, constructed in accordance with my application SerialNo. 463,686, may be mounted for rotation on a wire rope or cable 10which extends at an angle between an eye bolt 11 on an anchor 12 andthrough a pulley 13 attached to an eye bolt 14 mounted on a post 15,with a counterweight 16 attached to the free end of cable 10 to permitthe cable 10 to be drawn partly through Patented June 6, 1961 the pulley13 as a steer moves against the applicator A. The anchor 12 may be arelatively short post embedded in the ground 17 and the post 15 may alsobe embedded in the ground 17. As will be evident, the steer may moveunderneath the applicator A to permit the same to roll along his backand part of one side, although it will be understood that when the steermoves under the applicator from the opposite direction, the applicatorwill roll against part of its opposite side. Also, the steer may moveforwardly against the applicator with its chest and also may step overthe applicator to rub its belly and a portion of either side against theapplicator. Of course, by

backing into the applicator, the steer may engage the same.

with his rear legs and buttocks, while its ears and neck may be readilyengaged as well as its chest. The tendency for steers and other animalsto rub against posts, fences and the like is well known, and thistendency is taken advantage of in placing the applicator at such anangle,

may include a mineral oil base and a suitable insecticide.

for ridding the animal of insects, such as lice, flies, ticks, grubs andthe like. Insecticide suitable for addition to the mineral oil baseinclude pipernyl butoxide and pyrethrins, as for dairy cattle, or DDT,DHC and rotenone for range cattle, or any other desired type ofinsecticide. The mineral oil may be a paraflin base oil of approximately10 or 20 SAE.

The applicator A includes a self feeding reservoir R at the upper end, aclamp 18 being mounted on cable 10 above and below the applicator A tolimit longitudinal movement thereof, if desired, although the principallongitudinal support for the applicator comprises a clamp 19 inside thesame, as in FIG. 2. Clamps 18 and 19 may be cable clamps, or sleevepressed onto the cable by several. tons pressure. The applicator alsoincludes a wick roll 20 of matting, preferably cattle hair and jute,which appears to hold the oil better than other types of absorbentmaterial.

In accordance with this invention, the roll 20 may be formed by taking asection of matting, such as three feet long and six feet wide, folding alayer of burlap 21 over the same, as in FIG. 4, and attaching a piece ofadhesive tape 22 to one side of the burlap covered matting and to thecable 10. Tape 22 may be formed of plastic or other suitable materialprovided with a layer of adhesive on one side, masking tape beingparticularly suitable for the purpose. Preferably, one adhesive edge ofthe tape 22 engages one side of the burlap covered matting and theopposite adhesive edge of the tape engages the cable 10, which need notbe completely surrounded, although the tape may be applied in any othersuitable manner. When thus held by the adhesive tape, the matting isrolled, as in FIG. 5, onto the cable 10 to the desired dimension, as byturning the cable 10, and then secured at several points by bindertwine. Then a jacket 23, preferably formed of relatively heavy wovencotton, as of the type normallyused as a fire hose covering, is slippedover the roll. Then, a reverse twist may be given to the cable10, sothat the portion of the adhesive side of tape 22 formerly secured to thecable 10, will unwind from the cable and onto the burlap 21, therebyfreeing the cable from the tape and permitting the roll to rotate aboutthe cable, as well as move longitudinally thereof, particularly sincethe nonadhesive side of the tape provides a smooth surface against thecable. It will be noted that, with the adhesive side of the tape againstthe burlap, the tape will not tend to be dislodged irrespective of thedirection of rotation of the roll relative to the cable. In addition,when the roll becomes saturated with the insecticide solution,

particularly when a mineral oil is utilized, the solution will also actas a lubricant to permit greater freedom of movement of the roll aboutthe cable. It will be noted that the roll may turn or move relative tothe cable, even though it is tightly wound onto the cable, and that suchmovement is of particular advantage during use, since the portion of thejacket 23 contacted by the animal will be continuously changed, therebyadding to the useful life of the jacket.

The jacket 23 is preferably longer than the length of the roll ofmatting 29 extending over the same at both ends, so that a wooden plug24 may be slipped within the lower end of the jacket 23 and thereservoir R slipped within the upper end. Prior to the latter, a portionof the matting may be cut away at the upper end to receive the clamp 19.A metal strip 25 fastened by a clamp 26, such as of the Band-I type, maybe utilized in clamping the jacket 23 securely to both the wooden plug.24 and the reservoir R.

The reservoir R, as in FIG. 7, maycomprisea central pipe or tube 30,which extends centrally of and past each end of a cylindrical container31, conveniently formed of light steel, such as l6-gauge, and issoldered, brazed, welded or otherwise suitably attached to the tube 30.In addition, a connection 32 for a filling plug 33 may be welded, brazedor otherwise suitably mounted in the side of container 31 adjacent theupper end thereof. Connection 32 conveniently comprises one-half of asmall pipe union, the same nominal size as plug 33. The container 31 isfilled by removing plug 33, pouring ahalf gallon or the like of theinsecticide solution into the contaier, and then replacing plug 33.

After the plug 33 is replaced, the only exit for the solution fromcontainer 31 is through a small hole 34 in pipe 30, inside but adjacentthe lower end of the container 31. The solution is discharged from thereservoir R only as it is used up, by being agitated throughuse. This isdue to the fact that the oil base. insecticide does not tend to flowreadily through hole. 34, since a vacuum is produced in container 31 andis not broken at hole 34 until .the container is agitated. suficientlyto cause one or more air bubbles to move from hole 34 to the top of thecontainer through the solution. Thus, when the. tube 31) is agitated,drops of the insecticide solution will be discharged through hole 34,and will move down along the cable to saturate the matting 2i From theforegoing, it will. be evident that the. method of forming a roll ofabsorbent material on a cable, in accordance with this invention,fulfills to a marked degree the requirements and objects hereinbeforeset forth. As Will be evident, the use of adhesive tape, such as maskingtape, in initially attaching the end of the layer of absorbent materialto the cable, for rolling the same thereon, is inexpensive, and verysimple to use. Also, the edge of the absorbent material is held to thecable while being rolled thereon, so that the roll may be made as tightas desired. A reverse twist of the cable, after the roll has been madeand secured, is a relatively simple expedient, but produces extremelyvaluable results. Thus, not only is the roll free to move relative tothe cable, both rotationally and longitudinally, but the reverse twistof the cable causes the adhesive side of the tape to adhere to theinside of the roll of absorbent material, while the non-adhesive side ofthe tape provides a smooth surface for movement along and about thecable.

While this invention has been described with particularity in connectionwith the forming ota roll for use in an animal insecticide applicator,it will be understood that the method may beutilized in forming othertypes of rolls which are to be wound. relatively tightly about a cablebut relative movement between the roll and the cable is desired. It willalso be understood that the terms cable and absorbent material, as usedin the appended claims, are not limited strictly to what might becalled, from a commercial standpoint, a cable or absorbent material,respectively, but encompass the equivalents thereof, particularly anyelement which might be substituted for a cable to form a center forrotation for the roll, whether flexible or non-flexible, and anymaterial adapted to form a roll. It will also be understood thatvariations in the steps of the method of this invention may be employed,all without departing from the spirit and scope thereof.
